摘要
为探寻电站群的最优运行方案,以获得更好的经济效益,创新地提出了一种基于历史数据的经济运行生产指标的统计分析方法,首先提取较优的历史数据,再对其进行加工计算和对综合效率系数K值进行拟合,并使K值函数动态化,使其不仅具有良好的自适应性,还可以随着数据的继续积累,样本量增大,误差会越来越小,精度越来越高,可更好地指导生产,进一步提升梯级电站群的优化调度水平.
Abstract
In order to get the optimal operation scheme for power station group and achieve better economic benefits,an innovative statistical analysis method for economic operation and production indicators is proposed based on historical da-ta.Firstly,the historical data with good quality is extracted and processed.Then,the comprehensive efficiency coeffi-cient K value is fitted and the K value function is transformed to a dynamic mode.It not only has good adaptability,but also able to improve the accuracy with data accumulated and sample size increased.Thus,it can guide the production process better and further improve the optimization dispatching level of cascade power station group.
